I was put off Windows Vista by all the negative talk, but I decided bite the bullet with my latest laptop.
If you get 3 or 4 gigs of memory, which isn’t all that expensive these days, it seems to work just fine. It’s actually faster than my second-oldest laptop which is running XP Pro.
Windows was built so the 4th gig was wasted, but the word is that Vista SP1 will be able to use it. I don’t know; I haven’t had time to download the service pack yet.
I don’t think upgrading an old computer makes much sense. The technology changes so fast, it’s more practical just to buy a new computer with the new OS on it.
A 32-bit OS cannot reference more than 3.5G of RAM because of the size of the address. You need 64-bit Vista or XP to see 4 gig or more.
Not only that, Vista is basically a DRM (Digital Rights Management) platform.
The purpose of Vista was not to deliver more power and performance to the user, but less.
The "improvements" were all for Microsoft's benefit, not their customer's.
